2013 BMW 5 Series GT Range: New Features

Across the 5 GT range, BMW's Driving Experience Control is now standard, adding the Eco Pro, Comfort and Sport modes to all models.

Accessed via a switch next to the gear lever, and depending on specification, the driving modes allow three choices of predefined steering, suspension and drivetrain configurations.

Safety features have also been upgraded, with the Active Protection Safety Package now fitted as standard.

The APSP system identifies potential collisions either through the font-mounted camera, or by radar, along with deliberate emergency braking or distinctive understeering or oversteering.

The system activates at 18km/h, tightening the seatbelt to eliminate slack. In a critical situation, the front seatbelts are tightened and the side windows and sliding sunroof closed.

In the event of an unavoidable collision, the system automatically slows the vehicle down. After the collision, the vehicle is brought to a halt through maximum braking force and then held for an additional 1.5 seconds, reducing the likelihood of a secondary collision.

BMW's Parking Assistant also joins the options list, along with a Bang & Olufsen audio system.
